composer/composer:php7 php eversion

[vasiliyb]

Folks, trying to run a throw-away container with php7.1

docker run --rm -v $(pwd):/app composer/composer:php7 install

However, I see errors thrown such as:

Problem 1
    - Installation request for doctrine/annotations v1.5.0 -> satisfiable by doctrine/annotations[v1.5.0].
    - doctrine/annotations v1.5.0 requires php ^7.1 -> your PHP version (7.0.7) does not satisfy that requirement.
  Problem 2
    - Installation request for doctrine/cache v1.7.0 -> satisfiable by doctrine/cache[v1.7.0].
    - doctrine/cache v1.7.0 requires php ~7.1 -> your PHP version (7.0.7) does not satisfy that requirement.

I'm not able to find the proper tag, how do i get php 7.1? Thanks!

Super quick solution: docker run --rm -v $(pwd):/app prooph/composer:7.1 install .

You can use the official composer Docker Container to use PHP 7.1 (and the latest composer version, too)!

It seems that the support for PHP 71 has been added, but the problem still exists :( Ty samjarrett for your solution ^)

Have same issue.
# docker run --rm -v $(pwd):/app composer/composer:latest install
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
- Installation request for symfony/cache v3.4.2 -> satisfiable by symfony/cache[v3.4.2].
- symfony/cache v3.4.2 requires php ^5.5.9|>=7.0.8 -> your PHP version (7.0.7) does not satisfy that requirement.
